I am reloading cast bullets for my Arisaka T38 rifle in 6.5 Arisaka cal.

Anyone use a Lee crimp die??? If so... should I get a custom made die or can I use another type of 6.5mm rifle Crimp die?? :think: :think:

I don't crimp FMJ bullets 6.5 Arisaka....

However, in 8mm Mauser and 7.62x54R... I use a Lee factory crimp die.

I should have mentioned that I only single load so there is no problem with recoil moving the bullets. Obviously if you are firing from a magazine it is a whole other kettle of fish.

If you crimp a cast bullet it hurts the accuracy . The more you crimp it , the more it shaves the bullet as it exits the case mouth .

Would this then not hurt accuracy on cast revolver ammunition. Such factory ammo is heavily crimped as are my great shooting reloads.

Accuracy levels are different between handguns and rifles , as are the velocity , distances ,twist rates and pressure . Plus what you are getting and thinking is great accuracy and my standards my be different . Crimping is never used in any rifle accuracy matches . It can help with the performance of poor quality handloads .

Check the Lee Precision site and see if they have any in clearance. Sometimes they over produce for a custom order and list them for clearance. That's how I got mine. I like to factory crimp with Lee after crushing a few cases early in my reloading days. You can adjust the firmness of the crimp to adjust for accuracy, just like a roll crimp. Both can be adjusted, so I cannot fathom what the difference would be if you experiment with it.

I have found the internal diameters of many dies to be woefully undersized, so crimping might be the least of your worries. I have my own gauge pins from .060 to .500 and have access to intra-micrometers which can measure to .0001" on inside diameters with three contact points. I'm seriously thinking of making my own neck sizers to take that out of play in my reloading. I already have for 45/70 and it worked great.

Best Regards,
